Major EAL manufacturer reassures: Railko and Feroform Bearings compatibile with bio oils (EAL).
Tenmat composite bearings are perfect for use with EAL systems due to their resistance to acidic conditions, which destroy white metal bearings. Major EAL manufacturer has conducted a range of extensive tests with Tenmat bearing materials. The results have confirmed a full compatibility of the materials with the conditions present when EALs are used.
THE PROBLEM WITH WHITE METAL BEARINGS AND EALS.
DNV GL reported a number of stern tube bearing and seals failures linked to systems running with white metal bearings and EAL lubrication. When white metal is used as a bearing material, it does not hold its properties very well in the acidic environment of some EALs. Moreover, white metal bearings are prone to corrosion and premature failure when exposed to seawater that enters the system.
TENMAT COMPOSITE BEARING MATERIALS COMPATIBLE WITH EALS.
Tenmat Feroform and Railko are materials specifically designed for stern tube oil and lubrication systems and are capable of replacing white metal bearings without the additional cost of a seal and shaft line coating.
They provide exceptional performance both in different types of EALs and seawater.
FEROFORM and RAILKO are composite materials fully approved by all classification societies and readily available for the next dry-docking anywhere around the world.
